We develop a model that combines competitive exchange of private commodities across endogenously formed groups with public good provision and global collective decisions. There is a tension between local and global collective decisions. In particular, we show that group formation and collective...

We analyze the implications of the structure of a network for asset prices in a general equilibrium model. Networks are represented via self- and mutually exciting jump processes, and the representative agent has Epstein-Zin preferences. Our approach provides a flexible and tractable unifying...

We analyze monopoly power in a market for a complementary fossil resource like oil in a two country/two period model with international trade in general equilibrium. Focusing on the complex interplay of capital and resource market, we elaborate how these effects feed back into the resource...

Motivated by a set of stylised facts based on provincial data for India, this paper investigates the incidence of urban poverty by modelling the impact of technological progress in the formal sectors of the economy on the urban informal wage in a four-sector general equilibrium framework with...

We sketch a model that shows how skill-biased technological change may reverse the classic Balassa-Samuelson effect, leading to a negative relationship between productivity in the tradable sector and the real exchange rate. In a small open economy, export goods are produced with high-skilled...

We investigate how adverse selection in the used capital market generates procyclical sales of used capital -- capital reallocation. In our model, adverse selection produces a resale discount for used capital. In equilibrium, this endogenous partial irreversibility is more severe in recessions...

Under risk, Arrow-Debreu equilibria can be implemented as Radner equilibria by continuous trading of few long-lived securities. We show that this result generically fails if there is Knightian uncertainty in the volatility. Implementation is only possible if all discounted net trades of the...

A rapidly rising carbon tax leads to faster extraction of fossil fuels and accelerates global warming. We analyze how general equilibrium effects operating through the international capital market affect this Green Paradox. In a two-region, two-period world with identical homothetic preferences...
